Evolutionary tree software

Hi,
I'm looking for a program which will determine the "evolutionary tree" of a num
ber of genes. This was done by Hanks, Quinn and Hunter(1988).Science,241,442-
452. They cited: Fitch and Margoliash(1967),Science 155,279.
and Feng and Doolittle(1987), J. Mol. Evol. 25, 351.
(Hanks et al. used it in a review of protein kinases)
Does anybody out there have or know where I could find this software?
To those of you who have been following my recent net saga, my advisor requeste
d that I find this! (there's a crack in the wall) Please help me show him how u
seful the net can be.
Thanks,
Dan
